<p>In Guinea the leaves of <em>Justicia flava</em> are used as a vegetable collected from the wild. They are cooked into soup or stew. The plant is also considered as a good forage. In Kenya the plant contributes to sand-binding vegetation in coastal dunes and sandy river banks and leaves are burnt to ash to produce a vegetable salt. In Tanzania the leaves are reported to be emetic, in Côte d’Ivoire haemostatic. Preparations are used on cuts and to treat menorrhagia, and blood in the sputum. The whole crushed plant, mixed with vegetable ash, seed of <em>Aframomum</em> species and capsicum pepper is administered by enema against painful menses, or, mixed with lemon juice, taken to induce menstruation. In Côte d’Ivoire the pulped leaves are rubbed on the skin to treat convulsions and feverish pains in babies. In Ghana the plant is used internally and externally against fever, yaws and diarrhoea in children. The inflorescence is said to be a cure for dysentery. An infusion of the plant is taken with egg albumen and coconut juice against palpitations of the heart and leaf sap is used as an eye lotion. In Tanzania leaf sap is taken against hookworm and to treat hydrocele, including bathing the affected parts. The bitter root is chewed by the Masai to cure diarrhoea and coughs.
